DE2918049C2 - Cleaning preparations, in particular for paint soiling caused by writing materials - Google Patents

Description

The invention relates to a cleaning agent, in particular for paint stains caused by writing materials, that essentially consists of solvents, emulsifiers, wetting agents and possibly other additives consists.

The generally known cleaning agents essentially have these basic components.

From DE-PS 12 57 319 a stain remover is also known that using a mixture of esters of the lower fatty acids with lower alcohols and / or with chlorinated hydrocarbons and / or higher-boiling ketones and ethers and an oxyalkylbenzene and, if necessary, additional natural or synthetic waxes or wax-like substances are produced.

Such a mixture is particularly useful for removal from stains, among other things, from copier pens and ballpoint pens from foils and others Plastic objects provided. The disadvantage here, however, is that with such a stain remover not all paint soiling caused by writing materials, and in particular those in textiles can be cleaned. In addition, such a cleaning agent is not completely

! 0 dig water-soluble, possibly easily flammable, incompatible with the skin and possibly even poisonous, so that its use is only possible to a very limited extent

In contrast, it is the object of the invention to create a universal cleaning agent for removing paint stains primarily caused by writing media, in particular also from textiles, which can be used by anyone without any problems and without risk.
This object is achieved in a surprising manner with a cleaning agent which has the features presented in the characterizing part of claim 1. In particular, by using a basic solvent mixture of water and alcohol in conjunction with a glycol ester as an additional solvent, and by assigning a wetting agent mixture of a quaternary ammonium compound and oxethylated alkylphenol to an aliphatic alkanolamine, in the stated quantity ranges of the components, it is surprisingly easy to almost Remove all currently commonly used dyes from soiling of writing material by simply treating them with the cleaning agent and then washing them out with water.
The subclaims represent particularly advantageous developments of the inventive concept.

For reasons of physiological harmlessness, the solvents should not be used of methanol can be dispensed with if the detergent is not for industrial or other commercial use Purposes, but intended for cleaning for household use. The mixed solvent of water and alcohol is used in particular to absorb and bind emulsified dirt and does this easy removal of the already bound dirt when washing out with water afterwards.

Glycol ester as a solvent component dissolves resins in particular and dissolves or loosens the bound ones Soiling from the subsurface. Because of its great affinity for many organic substances Butyl glycol acetate is particularly suitable.

Alkanolamines are known as cleaning, soap-forming substances that emulsify with fatty acids. in the Cleaning agents according to the invention, they also fulfill the function of an emulsifier, and they - and preferably triethanolamine - in connection with its reducing effect on various dyes influence the cleaning action of the agent in an advantageous manner. Let through their admixture also remove greasy paint stains and grease stains par excellence.

Practically all aliphatic amino alcohols (alkanolamines) are suitable as emulsifiers. In addition to triethanolamine are these z. B. also aminopropanol, methylaminopropanol, diethanolatnin, etc. Oxäthylierte alkylphenols are nonionic wetting agents as surfactants, which due to their affinity for certain groups of dyes in addition to their wetting properties as an emulsifier for fats and at the same time as a binder for

the dyes work. It has been shown that the Alkylphenols containing 10-ethylene oxide groups and, in turn, nonylphenol-10-polyglycol ethers, in the context of the mixtures according to the invention, are particularly suitable.

The quaternary ammonium compounds and preferably tetralalkylammonium ethyl sulfate from them the general formula

are, as surfactants, cation-active wetting agents and act, just like the oxethylated alkylphenols, due to their affinity for certain groups of dyes, apart from wetting and emulsifying for fats and the like, also as "Binder" for the dyes.

20 The consistency of the cleaning agent can be changed as required by varying the individual components or by adding a thickener such as B. cellulose ether, can be changed from more or less liquid to pasty or solid state without the cleaning effect being adversely affected.

With the cleaning agent according to the invention, in particular, bound and unbound paint soiling can be removed Easily dissolve on textiles and leave no residue after treatment with water Wash out, as the cleaning agent itself is completely water-soluble and the soiling is so strong emulsified that they can be removed by water.

In the same way, soiling of the skin can be removed just as easily as color impurities on leather, plastics, wallpaper and the like.

For skin cleansing, however, it is advisable to wash the skin thoroughly with water immediately and then, if necessary, apply greasy skin care products to the cleansed areas of the skin.

The invention is explained in more detail below with the aid of a few exemplary embodiments shown in tabular form explained.
